The complete House M.D. series contains 177 episodes.
Those episodes were broadcast across eight seasons on Fox between November 16, 2004, and May 21, 2012. The series centers on Gregory House and his diagnostic teams at the fictional Princeton-Plainsboro Teaching Hospital. Most episodes combine a self-contained medical mystery with continuing stories about House, his colleagues, and the consequences of his decisions.
The total includes the two-part episodes that were broadcast as separate installments. It also includes the series premiere, “Pilot,” and the finale, “Everybody Dies.” Episode totals can vary in informal listings when specials, recap programs, or international broadcast arrangements are counted differently, but standard series references list 177 episodes.
The number is easy to confuse with the season count, which is eight, or with individual season totals. House M.D. was a conventional network drama with many full-length seasons, so the complete episode count is much larger than the number of seasons. The final episode aired in 2012 after the show’s long run as one of Fox’s major scripted dramas.
